Mercedes Settles U.S. Emissions-Cheating Cases for $150M

Mercedes-Benz Group and its U.S. attachment have agreed to pay nearly $150 million to resolve multi-state suits over allegations that the automaker installed emissions-infidelity software in diesel vehicles vended across the United States. The agreement, blazoned on December 23, 2025, involves 48 countries, Puerto Rico, and the District of Columbia, and brings to a close times of action related to diesel emigration manipulation, emigration norm violations, environmental regulations, Mercedes diesel vehicles, and U.S. state agreements. 

The agreement requires Mercedes to make an immediate payment of $120 million to sharing countries, while a fresh $29.6 million has been suspended and may be reduced depending on the company’s compliance with vehicle form and junking conditions. State attorneys general said the overall value of the agreement, including consumer compensation and extended guarantees, could reach as high as $347 million, emphasizing the scale of the contended misconduct tied to diesel emissions cheating, software manipulation, BlueTEC diesel models, environmental compliance, and automotive suits.

Background of the Emigration Allegations

The suits stem from claims that Mercedes installed software in more than 200,000 diesel-powered vehicles vended between 2008 and 2017. According to agreement documents, the software enabled the vehicles to descry when they were witnessing sanctioned emigration testing and temporarily reduce emigrations to meet nonsupervisory norms. Under normal driving conditions, still, emigration situations were allegedly more advanced than fairly permitted.

Examinations into Mercedes’ diesel vehicles boosted around 2018, as controllers began checking the automaker’s BlueTEC II diesel technology. By August 2023, more than 39,000 of the affected vehicles were still on U.S. roads, according to statements from state attorney general services involved in the agreement. These vehicles included 15 models of diesel passenger buses and vans produced between model times 2009 and 2016.

Terms of the Multi-State Agreement

Under the agreement, Mercedes is needed to give fiscal relief to both countries and consumers. In addition to the $120 million outspoken payment to countries, the automaker must pay $2,000 to eligible possessors and lodgers who bring their vehicles into compliance with emigration norms. The company is also obliged to offer extended guarantees for affected vehicles, which some countries estimate to be worth about $1,200 per vehicle.

The suspended $29.6 million portion of the agreement can be reduced if Mercedes repairs, buys back, or removes affected vehicles from the request. For each vehicle addressed in this way, the company can reduce the suspended penalty by $750. The agreement also prohibits Mercedes from dealing with unborn diesel vehicles equipped with software designed to bypass emissions regulations.

Mercedes’ Response and Legal Position

In a statement released alongside the agreement advertisement, Mercedes said the agreement resolves “all material remaining legal proceedings related to diesel emigrations in the U.S.” The automaker emphasized that settling allows it to avoid prolonged and expensive court battles. Still, Mercedes maintained that the allegations are unsupported and denied any admission of liability.

The company also stated that it has formerly made sufficient fiscal vittles to cover the anticipated total costs of the multi-state agreements. This includes not only the payments to countries but also consumer compensation and bond extensions needed under the agreement.

State officers condemn misleading marketing.

Several state attorneys general used the agreement advertisement to condemn Mercedes’ marketing of its diesel vehicles as environmentally friendly. Alaska Attorney General Stephen Cox said the company promoted these vehicles as green druthers.
despite allegedly knowing they didn't meet emigration norms under real-world conditions. He described similar practices as deceptive to both controllers and consumers, stressing that violations of environmental laws carry serious consequences.

Washington Attorney General Nick Brown stressed the consumer benefits included in the agreement, noting that extended guarantees and cash payments significantly increase its overall value. According to Brown’s office, when all factors are considered, the agreement could reach $347 million.

Broader environment in Diesel Emissions Enforcement

The Mercedes agreement is part of a broader surge of enforcement conduct against automakers indicted of using emissions-infidelity software. The technology at the center of the allegations was developed by German engineering establishment Robert Bosch GmbH, which paid $98.7 million to U.S. countries in a 2019 agreement. Other automakers have faced indeed larger penalties, most especially Volkswagen, which agreed to a $570 million agreement in 2016, and Fiat Chrysler, which settled analogous claims for $72.5 million in 2017.

Arizona and California weren't parties to the recently blazoned agreement, as Mercedes had preliminarily settled diesel emigration claims with those countries. The company has also resolved affiliated action with the U.S. Department of Justice and the Environmental Protection Agency.

Counteraccusations for the Auto Industry

The agreement reinforces the growing scrutiny automakers face over environmental compliance and emissions transparency. Controllers and state officers have gestured that deceptive practices tied to emigration testing will continue to draw aggressive legal action. For Mercedes, the agreement marks a significant step toward closing a controversial chapter in its U.S. operations, while for the broader automotive industry, it serves as a memorial that violations of immigration laws can carry substantial fiscal and reputational costs.
